logger.rb: Fix handling progname

2017-07-20T16:47:26+00:00

Because progname was memoized with ||= a logger call that involved
outputting false would be nil. Example code:

  logger = Logger.new(STDOUT)
  logger.info(false)  # => nil

Perform an explicit nil check instead of ||= so that false will be output.

logger: fix monthly log rotate with DST

2016-10-08T00:06:57+00:00

* lib/logger.rb (Logger::Period#next_rotate_time): fix monthly log
  rotate when DST is applied during a month of 31 days.
  [Fix GH-1458]

With DST the month of october can actually last more than 31 days.
It can last 31 days plus 1 hour. So during october, `t` used to be
equal to "2016-10-31 23:00:00" instead of "2016-11-01 00:00:00".
This was then normalized to "2016-10-01 00:00:00" which lead every
single line of log during october to rotate the log file.
This fix ensure that next_rotate_time(now, 'monthly') always return
the first day of next month in every situation.

* test/logger/test_logdevice.rb (TestLogDevice#test_shifting_period_suffix):

2016-05-01T14:56:45+00:00

  too many shifting.  the last shifting created logs named as `*.3`, and
  they were never unlinked.
